• We report a new technique for fabricating organic-free luminescent thin films from solution-synthesized surfactant-capped nanocrystalline semiconductor quantum dots with a core/shell structure. Colloidal solutions of CdSe/ZnS nanocrystals with diameters of 2.1 to 5.1 nm were made into ion beams and deposited on polycrystalline substrates under high vacuum; we applied the ion beam direct deposition technique with an electrospray ionizer, supersonic jet emitter, and energy analyzer. The nanocrystalline structure was preserved in the thin films; the photoluminescence spectra were identical to those of the source solution, although the thin films were essentially surfactant- and solvent-free.
